20 Claims.

This invention relates to an automatic machine for forming hollow articles of glassware. More .particularly, the invention provides a new and improved automatic machine for blowing narrowneck bottles. The machine is of the general class wherein a charge of glass is first formed into a hollow blank or parison in a blank mould and is then blown to finished form in a blow mould. It is radically different'in many respects, however, from conventional narrow neck machines, as will be pointed out hereinaften It is an object of the present invention to provide an extremely simple narrow neck machine, characterized by high eificiency and a high rate of production.

In order to simplify the construction and to.

make the machine compact and highly efficient, the invention provides a single table, continuously rotating machine having a plurality of moulds mounted opposite each other on the single table.

One of the principal objects of the invention is to improve and simplify the transfer of a parison from its position in the parison mould to its position in the blow mould. To this end, the machine obviates the necessity of inverting and re-' verting the parison mould or the parison. In.- stead, the bottles are formed in an inverted position, from beginning to end. In this respect, the machine of the present invention is an improvement on my prior Patents Nos. 998,824, 1,072,553 and 1,491,369.

It is a further object of the invention to obviate the use of a neck ring as a means for supporting the parison during its transfer from the parison mould to the blow mould. Instead, the parison is supported by a suction head engaging its bottom during the transfer. The inner periphery of 40 the neck finish is in engagement with a steadying member during the transfer, to prevent lateral movement of the neck under the influence of centrifugal force resulting from rotation of the table, but this engagement will not deform the finish.

improved and simplified take-out means for the finished bottles.

It is a further object to provide cam-operated means for performing the various steps in the manufacture of the bottles, all of said means being provided with resilient safety features to prevent jamming of the machine or breakage of parts, in the event that molten glass or cullet shouldbecome lodged between any of the operative parts.

pairs of permanently inverted parison and blow It is a further object of the invention to provide sets of moulds.

Other and further objects and advantages of the invention will be apparent to one skilled in the art upon consideration of the following description of the illustrative embodiment of the invention shown in the accompanying drawings.

Referring particularly to Figures 1, 3 and 4, the machine is supported from a base In which may be provided with wheels adapted to run on 45 tracks or the like, in order that the machine as a whole may be moved to and from operative position with respect to a glass feeder. Projecting upwardly from the base and bolted or otherwise secured with respect thereto, is a stationary 001- 50 umn ll having a horizontal annular flange l2 which serves to support a ball bearing assembly l3. Above the upper race H of the assembly,-

is the lower ring N3 of a rotatable column. The rotatable column is built up from a plurality of superposed sections comprising the lower ring |5, an intermediate gear I6, and an upper annular member l1. The upper ring I1 is provided with a lower horizontal annular flange l8 and a plurality of vertically disposed plane faces IS, the latter being drilled at 20 to receive bolts 2| or the like adapted to secure the table sections 22 thereto. Each table section comprises an inner, vertically disposed backing plate 23, a horizontal top portion 24 and a vertically disposed reinforcing web 25. In the present embodiment, the machine comprises ten pairs of moulds and the table is made up of ten sections 22.

The stationary inner column II is provided with an intermediate reduced portion 26 which supports a stationary cam plate 21, the structure and function of which are hereinafter described. Above the portion 26 is a still further reduced portion 28 adapted to serve as the inner wall of an air chest, as described below. At its upper end the stationary column I supports an annular top member 29, which carries a second horizontally projecting cam plate 36.

Above the portion 26 of the stationary column II, and opposite the portion 28 thereof, there is rotatably mounted an annular sleeve 3| having an annular recess 32 formed on its inner face. A plurality of spaced passages 33 lead outwardly and upwardly from the chamber 32, through a horizontally flanged portion 3| of the sleeve 3|. A central vacuum pipe 34, provided with a branch nipple 35, extends downwardly through the stationary column The branch 35 communicates with the annular recess 32 and with each outwardly disposed passage 33.

A second rotatable sleeve 31, having an annular recess 38 formed on its inner face, is disposed around the upper end member 29 of stationary column The recess is in communication with a passage 39 formed in the member 29 to which blowing-air is admitted by the pipe 40. The sleeve 31 is clamped between rings 4|, 42 and the latter is provided with a plurality of outwardly projecting arms 43 having bifurcated ends embracing posts 44, upstanding from the sleeve 3|, whereby rotation is imparted from the rotatable sleeve 3| to the sleeve 31. A plurality of pipes 45 or the like communicate between the annular recess 38 and the several blow heads, as hereinafter described.

The flange 3| of the sleeve 3| supports a plurality of bifurcated, upstanding brackets 46, bolted or otherwise secured thereto. An outwardly projecting hollow arm 41 is pivoted on each bracket 46 and the arms and brackets are provided with air passages 48, 49 registering with the passages 33.

"Each table section 24 carries a pair of upstanding posts 50, supporting a crosshead 5| at their upper ends. Each crosshead 5| has associated therewith, an upwardly projecting, vertically slotted bracket 52. The vertical slot in each bracket 52 embraces the outer end of its arm 41 and prevents relative lateral movement of the latter. Thus, as the table turns, rotation is imparted by the brackets 52 to the arms 41. The sleeve 3| rotates the sleeve 31, as hereinbefore explained. As a result, all of the rotatable parts supported on the stationary column rotate in unison.

The moulds and their operating mechanism will now be described. Since each pair of moulds is substantially identical to the others, a description of one will suflice.

Each table section 24 is provided with a pair rounds the shaft 15.

of vertically disposed radially aligned posts 55, 56, upon which the moulds are pivotally mounted. The post 55 is mounted in a bracket 51 and a similar bracket 58 supports the post 56. The parison mould holders 59, 59' have arms 60 which are pivotally mounted on the post 55 and the blow mould holders 6|, 6|- are likewise mounted on the post 56 by means of arms 62. The parison mould halves 63, 63 may be secured in the mould holders in any appropriate manner, and the same is true. of the blow mould halves 64, 64. The parts are so constructed that the parison moulds and the blow moulds are alternately pivoted or swung to closed position about the same moulding axis.

The moulds are opened and closed by means of vertically disposed stub shafts journalled in and extending above and below the table sections 24. Referring to Figures 1 and 8, the movements of the parison mould are controlled by shafts 65, 65' journalled in upstanding sleeves 66, 66'. The rotatable shafts 65, 65' carry at their upper ends lever arms 61, 61, connected to the parison mould holders by links 68, 68, whereby when the shafts are oscillated, the parison moulds are opened and closed. As indicated in Figure-8, the lever arms 61 and their associated links 68 are preferably brought into alignment, in dead center position, when the moulds are closed.

The lower ends of the shafts 65, 65' carry lever arms 69, 69', attached at their ends to connecting rods 10, 18'. As shown in Figures 3 and 8, the rods 10 are secured at their inner ends to a downwardly projecting post 1| which is secured to a slide 12 mounted on the table section 24, between guide flanges 13, 13'. Each slide 12 carries, on its upper side, a cam roller 14, disposed in operative relation to a cam track associated with the plate 21, as hereinafter described.

The connecting rods 10 are provided with resilient safety devices. Each rod comprises an inner shaft 15, bent slightly at its outer end and pivotally connected to the lever 69. A sleeve 16 provided with an open, yoke portion 11, sur- The inner end of the shaft isprovided with bolts 18 and a coil compression spring 19. The spring is interposed between the bolts 18 and the base of the yoke portion 11. The sleeve member 16 is extended at its inner end 8|, and is connected to the post 1|, as aforesaid. It will be seen, therefore, that an inwardly directed pull from the slide 12 will be transmitted through the spring 19 to the shafts 65 to close the parison mould. If, for any reason, the mould should be prevented from closing, a resilient lost motion connection is provided between the shaft 15 and the sleeve 16, whereby breakage of the parts is prevented.

The means for opening and closing each blow mould is similar to that described above. A pair of vertically disposed stub shafts 85, are journalled in upstanding sleeves 86, 86. The shafts carry at their upper and lower ends, respectively, lever arms 81, 81', 89 and 89. Links 88, 88' connect the upper levers to the blow mould holders. The lower lever arms 89, 89 are pivotally attached to the outer ends of connecting rods 98, 90'. The inner ends of the connecting rods 90, 98 are secured to a downwardly projecting post 9|, carried by a slide 92 disposed on the table 24 and guided by the flange guide members 13, 13'. Each slide 92 supports on its upper surface, a cam roller 94 disposed in enopening and closing movement.

gagement with a second cam track on the plate 21.

The connecting rods 90, 90' likewise embody resilient safety features. These members are each made up of an inner shaft 95 having an abutment sleeve 99 secured thereto. The rod 95 is telescopcd inside of a sleeve 91, the latter being connected at its inner end to the post 9|. The sleeve 91 has a yoke portion 98 formed therein, in which the inner end of the shaft .95 is disposed. Nuts 99 are threaded on the inner end of the shaft 95 and disposed in the opening in the yoke portion. A coil compression spring I is disposed between the outer end of the sleeve member 91 and the abutment ring 99, fast on the shaft 95. Thus, the force serving to close the blow mould, upon an outward movement of the connecting rod 90, is transmitted through the spring I09. If the mould is prevented from closing, the spring will be compressed to avoi the breakage of any of the parts.

The cam plate 21 is provided witha plurality of downwardly projecting flanges, forming cam tracks for the rollers 14 and 94. As shown in Figure 3, four flanges IOI, I02, I03 and I04 are shown, but it will be understood that only two flanges, such asthose indicated by reference characters IOI and I03 are essential, because, in that view, the slides 12 and 92 are both in their innermost positions, holding the parison mould closed and the blow mould open. Referring to Figures '1 and 9, the cam plate is slotted or otherwise cut away at four spaced points, and end members I05, I06, I01, I09 are bolted or otherwise secured in place. These membeis having downwardly projecting flanges associated therewith which act as continuations of the flanges on the main cam plate. Thus, the end member I05 will shift each roller 14, successively, from its position in engagement with flange IOI outwardly into engagement with the downwardly projecting peripheral flange I09, as shown in Figures 4 and 9. The opposite end member I06 will subsequently draw the roller 14 inwardly, again to engage the flange I9I, when the parison mould is to be moved to closed position. The cam end member I01 will shift the blow mould operating rollers 94 from engagement with the track I03, outwardly into engagement with the downwardly projecting flange IIO (Figs. 4 and 9) to close the blow moulds and maintain them in closed position. The other cam member I09 draws the rollers 94 inwardly, to cause them'to open the blow moulds and to reeng'age the flange I03 to hold them open.

The cam end members I95 .I08 may each be mounted for adjustment, circumferentially of the plate 21, to change the timing of the mould Moreover, the end members may be readily removed from the machine and differently shaped cam members substituted therefor, to effect adjustments in the operation of the machine.

The means by which a charge of glassis formed into a parison in the parison mould will now be described.

Referring to Figure 3, a charge of glass may be dropped into the parison mould 63 through the oscillating funnel II5, described below.

The charge is compacted in the lower, neck finish end II6 of the parison mould by creating a vacuum at that end. Each table section is proan initial blow opening in the charge, and means for applying blowing-air thereto. The blow head assembly (Fig. 5) includes an outer cylindrical casing II1, an inner cylindrical member II9, terminating at its upper end in a top flange H9, and a cap I29, shown in detail in Figures 11 and 12, and described below. The space I2I between the inner and outer cylindrical members H1, H9 provides a vacuum passage leading upwardly through bores I22 and I23 to the suction grooves I24 formed on the meeting faces of the parison mould halves. The neck finish inserts I25 are preferably so constructed that a small space is provided between their meeting faces, to permit the application of vacuum from the grooves I24 directly to the glass in the flnish forming portion of the parison mould.

The outer casing II1 of the blow head carries a valve housing I26, connected to a pipe I21 leading. to an annular recess I29 (Fig. 3) formed on the inner face of the movable column section I5. The central vacuum pipe 34 (Fig. 4) is provided with a branch conduit I29 at its lower end, communicating. with the annular recess I29, whereby a partial vacuum is created in the recess, in the pipe I21, and in the space I2I between the concentric cylindrical casings H1, H8, Figure 5.

The application of suction to the chamber I2I is controlled by a valve I30, rotatably mounted in the casing I26, and provided with a transverse bore I3I, as shown in Figure 5. A four-pointed trol its movement. A pair of stationary, adjustable rollers. I33, I34 (Figs. 1, 2 and 3) are disposed adjacent the feeding and compacting stations to engage the star wheel and turn it through a quarter of a revolution. The flrst roller I33, therefore, turns each valve I30 so as to apply suction to the lower end of the parison mould, and the second roller I34, again closes the valve, to terminate the suction.

Blowing-air is applied to each blow head from one of the pipes 45 (Fig. 1) through continuation pipes I35, which extend through the outer casing H1 and into the spaces interiorly of the inner casings H9. The cap piece I20 (Figs. 5, 11 and 12)' at the upper end of each blow head, is provided with a central threaded bore in which a mouth finish forming nipple I36 is secured. A

blow opening in the charge. The pin is mounted on the upper end of a cylindrical, plug-like valve body I39, slidably mounted in the cylindrical interior of the inner casing II9. A stem I39 depends from the lower end of the body I39 and is attached to a vertical slide- I40, having an outwardly projecting roller I4I on its lower end. The roller I4I rides on a cam track I42, which controls the position of the valve body I39 and the neck pin I31.

The neck pin and the valve body I39 assume three normal positions. When in their uppermost position, the pin is projected upwardly throughthe nipple I36 to form an-opening in a charge of glass when. the latter is compacted in the neck finish end of the parison mould. When in this position,'-the valve body I39 cuts off the blowing-air by closing the end of the pipe I35. When the body is moved downwardly to its intermediate or neutral position, as shown in Figure 5,

,the neck pin is withdrawn, but the blowing-air iswQll cut Offw When in its lowermost position, the valye body 138 uncovers the pipe I and blowing-air flows upwardly through the nipple .5 2,205 I36 to blow a charge of glass into a ho flow parlson, or to blow a parison into a finish bottle;

As shown in Figures 2, 2a and 3, the movement of the valve body I38 and the slide I40 is controlledby a roller I M riding along a cam track represented generally by I42. A portion I42a of this track is pivoted at M21) in a bracket M20, and pressed upwardly by a spring I42d. The pivoted track section serves to project the valve body and the pin I38 to the uppermost position, as shown in Figures 3 and 13. The spring I42 provides a resilient upwardly directed force to hold the parts in their upwardly projected position, and the force is sufficient to hold the parts in normal operative position, but the spring will prevent breakage of the parts if the pin is prevented from moving to its normal uppermost position. The bracket I 420 includes a downwardly inclined, overhanging track portion I42e, adapted to pull the roller I4I downwardly into the lowermost, blowing position shown diagrammatically in Figure 14. The cam track I42 (Fig 2) has an upwardly inclined portion I43, merg ing with a horizontal portion I44, and serving to raise the roller I4I from the lowermost, blowing position to an intermediate, neutral position,

substantially as shown in Figure 5.

The bracket M20 is preferably longitudinally or circumferentially adjustably mounted on the track I42, to effect changes in the timing 'of the movements of the roller MI and valve I38.

As stated above", air for blowing the charge of glass into the form of a hollow parison and for blowing the parison into the form of a finished bottle, flows upwardly through the hollow interior of the inner casing II8, through the depending portion I20' of cap I20, and through the nipple I36. As shown in Figure 12, the cap I20 is preferably mounted'for limited vertical movement with respect to the top flange II!) of the inner casing II8. A pair of pins 8' project upwardly from the top flange and extend through appropriate openings in the cap I20.

'The depending portion I20 of cap I20 is in tight sliding fit with the central bore in the top flange, H9. The undersurface of the nipple I36 is inclined as at I 36a, and is adapted to be engaged by a similar surface formed in the lower end of the parison and blow moulds. Therefore, when the moulds close about the nipple I36, the cooperating inclined surfaces mate with one another, to raise the nipple and the cap piece I20 slightly, so that the finish forming rib I36 of the nipple is brought into exact registry with the adjacent surfaces of the mould.

It will be noted that the parison moulds and the finish moulds shown in the accompanying drawings, both have open bottoms. The present invention includes a novel type of closure for the open bottoms of the moulds.

As shown particularly in Figures 5 and 6; each hollow arm 41 carries, at its outer end, a down- Wardly projecting suction head I45, adapted to project into and close the open bottom ends of the inverted parison and blow moulds. Each suction head is provided with an inner core member I46 centrally and laterally bored at I41 and I41 and communicating with an annular space I48. The core member I46 is secured in a vertical opening at the end of arm 41 by a nut I46. The suction head also includes an outer, lower sleeve I48, screwed to the core I46, and defining the outer surface of the annular space I48. A partial suction may be applied from the interior of the arm 41 to the bottom face I49 of the suction ed end I51 of the pin I53 to hold the parts in either of one of two positions. Referring to Figure 10 (Sheet 5) the plate I55 is pivoted to a bracket I58 secured to the lower face of arm 41, adjacent the suction head I45. The plate is urged outwardly into contact with the pin I 53 by a compression spring I59 seated in a socket formed in the bracket I58. The pin is adapted to be moved to its upper position, to open the valve I50 by contact with the upper end of the parison mould, upon descent of the arm 41 and the blow head I45, as hereinafter explained. The pin is moved to its opposite position to close the valve when the arm moves to its upper limit of movement, by contact with an adjustable abutment I58 (Fig.1).

As heretofore pointed out, the arm 41 is pivoted on a horizontal axis in the bifurcated bracket 46, As shown in Figure 3, the bracket 46 has a vacuum passage 49 therein, terminating atits upper end in an inwardly facing opening 48. In Figure 4, the opening 48' which registers therewith, is shown. The openings are so proportioned that they are always in registry whether the arm 41 is in its upper or lowermost position. Thus, the hollow interior of each arm 41 is always in communication with the source of vacuum connected to the central pipe 34.

"Each arm 41 carries an upwardly disposed roller I60, adjustable longitudinally of the arm, and a downwardly projecting roller H. An upper cam track I62 is carried by the cam plate 30, and a lower cam track I 63 (Fig. 3) is supported above the stationary cam plate 21. The upper cam plate serves to move the arm downwardly into firm engagement with a stop screw I64 mounted at the lower end of the slot in the guide bracket 52. The lower cam track I63 raises the arm 41 and the blow head, for purposes hereinafter described.

Any convenient means may be employed for imparting continuous rotation, preferably in a clockwise direction, to the machine. As shown in Figure 1, a suitable speed change device I10 is provided with a gear I1I in mesh with the main gear I6, whereby continuous rotation at any desired speed is imparted to the table. The power transmission device I10 is preferably of a type having a lateral shaft I12 projecting therefrom. :Ihis shaft may be conveniently used as a means for timing the oscillations of the gob feeding funnel H5.

The funnel II 5 is preferably supported at the upper end of a stationary post I13 on a horizontally oscillating shaft I14. The shaft has a crank arm I15 at its rear end, connected to av link I16, which, in turn, is attached at its lower end to one arm of a bell crank lever I11, the other arm of which is connected through links I18 and I 19 and lever I 80 to a sliding plunger I8I, adapted to be reciprocated by the shaft I12, by means of a cam or eccentric I82. Thus, every time a parison mould comes to a charging position under the funnel II5, the latter will be oscillated on a horizontal axis, so that the lower end of the funnel moves with the mould a short distance. This conjoint movement will be suflicient to guide the lower end of a rapidly falling gob of glass into the parison mould.

In Figure 9, the cycle of operation of the machine of the present invention is diagrammatically illustrated. Figures 13 to 17 showthe several stages in the manufacture of a bottle. At .position A, Figure 9, a gob is fed into a parison mould by the funnel H5, and immediately prior to the reception of the gob,'the star Wheel I32 has been turned by the roller I33 so as to apply a vacuum to the lower end of the mould. Consequently, as soon as the gob is received in the mould, the glass will be drawn downwardly into the neck finish portion, around the end of the neck forming pin I31, which, at that time, is in its upwardly projected position. The vacuum pull down step is shown in Figure 13. The star wheel is then turned by the roller I34 to terminate the suction pull down. Simultaneously with this action, the suction head I is lowered to close the'upper open end of the parison mould. The lowering movement of the suction head pushes the pin I53 upwardly and opens the port I5I so that a vacuum is applied to the face of the suction head. At the same time, the neck pin I3! and the valve body I38 are pulled downwardly to their lowermost positions, thereby uncovering the pipe I 35 and permitting the flow of blowing-air upwardly through the nipple I36 into the interior of the parison, The parison is therefore blown upwardly in the parison mould to hollow form, against the suction head I45, as shown in Figure 14. This blowing operation is represented at B in Figure 9.

After the parison has been blown to hollow form, the neck pin I31 and the valve body I38 are raised to the intermediate position shown in Figure 5, cutting off the blowing-air. The pin I31, however, is not projected upwardly through the nipple I36. The parison mould is simultaneously opened by the action of the roller I4 entering the cam end member I05, as represented at C in Figure 9.

The blown parison is supported, during and after the opening of the parison mould, by the suction head I45, as shown in Figure 15. The lower end of the parison is held or steadied by the nipple I36 which has an upstanding annular rim I36 engaging the inner periphery of the finish. Thus, the transfer is efiected throughout the portions of the cycle represented by C and D in Figure 9. In the present machine, there is, in reality, no transfer of a parison from a blank mould to a blow mould because, actually, the parison is relatively stationary and the moulds, rather, are transferred.

At the beginning of the portion of the cycle E, blowing-air is admitted to blow the parison to finish form. After the blow mould has been closed around the parison, the valve body I38 is again depressedto its lowermost position, thereby uncovering the port I35 and permitting the flow of blowing-air upwardly through the nipple I36 into the interior of the parison to expand the same to the form of the blow mould, as shown in Figure 16. The blowing-air preferably remains on throughout a substantial part of the cycle of the machine or until immediately before the blow mould starts to open.

As shown at F, Figure 9, the blow mould is opened by the entrance of the roller 94 into the cam end piece I 08. As soon as the mould is completely open, the cam I63 raises the arm 4'! and the suction head I45 to their upper limit of movement. Since the suction is still being applied to the lower face of the suction head and to the blow or bottle in contact therewith, the bottle will be raised upwardly with the suction head, as shown in Figure 17. The bottle will be held firmly in contact with the suction head until the suction is cut off. That action is accomplished when the pin I53 or the crosshead I52 strikes the adjustable abutment I58. carried at the upper end of the slotted bracket. 52. Preferably, a trough, chute, or other conveyor is positioned above the machine in position to receive the bottle when it is released by the suction head, to carry the same away to an annealing lehr or the like.
